To all 'whom t may concern.' A

Be it known that I, FRIEDRICH ALBERT RUNGE, a citizen of the UnitedStates, residing at San Marcos, in the county of Hays and State ofTexas, have invented certain new and useful Improvements in Air- Pumps,of which the following is a speciiication.

This invention relates to improvements 1n air pumps and its object is toproduce a simple and eiiicient device of this class that is cheap tomanufacture.

With the foregoing and other objects in view the invention consists inthe combination and arrangement of parts to be hereinafter fullydescribed in the following specification, pointed out in the claim andillustrated in the accompanying drawings which form a part of saidspecification and in which Figure 1 is a side elevation of my improvedpump. Fig. 2 is a front elevation. Fig. 3 is a fragmentary portion ofthe device, in section. Fig. 4 is a section taken on line 4 4 of Fig. 3.Fig. 5 isa section taken on line 5-5 of Fig. 3. Fig. 6 is a side view ofFig. 7 Fig. 7 is a front view of Fig. 6.

Like reference characters indicate corresponding parts throughout theseveral views.

The reference numeral. 1 designates a housing in which the greaterportion of the mechanism composing my invention is disposed and withinthe same I provide a storage tank 2 in which a close fitting piston head3 is disposed which is carried by a piston rod 4, about a portion ofwhich a spring 5 is disposed which rests upon said piston head. To thepiston rod 4 a pitman 6 is connected that is connected to the angularlink 7, supported in bracket 8 secured to the housing, which isbifurcated at one end to engage the clutch member 9 slidably keyed tothe shaft 10 journaled in the housing, and said shaft also looselycarries the clutch member 11, which carries the cog wheel 12, which isformed with the annular recess 13 in which the bifurcated end of theangular bracket 14 is disposed, said bracket being secured at itsopposite end to the cas` ing 1. A wheel 15 terminally carried by shaft10 is adapted to receive power from a belt (not shown) or the shaft maybe rotated by a crank if preferred. Within the casing 1 another shaft 16is journaled in the horizontal plane of the shaft 10 and said shaft 16is provided with a cog wheel 17 in mesh with the wheel 12, and withcranks 18, 18 that carry the pitmen 19, 19 secured to crossheads 20, 20slidably disposed in the casing 1, said cross-heads engaging piston rods21, 21 of pump cylinders 22, 22, which cylinders are connected by airpipes 23, 23 with the storage tank 2 which tank is provided with theusual air hose 24.

Operation: Rotation of shaft l0 will, through cog wheels 12 and 17,rotate shaft 16 which will operate the pump cylinders 22, 22 and causeair to be pumped into the storage tank. When the storage tank has beenfilled with air to its intended capacity the piston head therewithinwill compress the spring 5, which normally exerts a pull upon the pistonrod 4 to keep the clutch members in mutual engagement, against the topof the storage tank thus relieving the piston rod 4 of spring pressureand permitting disengagement of the parts 9 and 11 of the clutch, andwithdrawing the driving or motive power from the clutch member 11 andcog wheel 12 thus automatically stopping the operation of the pumpcylinders. Air from the storage tank may be withdrawn through hose 24 toinflate pneumatic tires or for other purposes.

at is claimed is 2- A pump of the type described, including an airstorage chamber, a plurality of air pumping chambers in communicationwith said air storage chamber, a drive shaft equipped with a fixedclutch member and a slidable clutch member, said clutch members beingarrangedfor inter-engagement, said storage cylinder or chamber havingarranged therein a piston whose rod or stem is equipped with a resilientmember, said resilient member being positioned intermediate the pistonand the piston cylinder head with the piston normally held spaced awayfrom said cylinder head by said resilient member, an angle lever having'movable connection with said slidable clutch member and a looselyjointed link connection between said lever and said piston rod, saidangle lever being arranged to be actuated by said resilient member todisengage said clutch member from said fixed clutch member at apredetermined position of the storage cylinder piston, a crankedcounter-shaft, ptmen as my own I have hereto affixed myrsignaand Crosshead connections between said ture in the presence of two subscribingcranked counteresheft and the pistons of witnesses.
